I ran DScaler on Win2K for about 6 months. I upgraded to XP, and now when I try to start DScaler, the initialize screen says that there is no hardware. I am able to get the WinTV software to work just fine with XP. I am using a GeForce 3 with the 21.83 drivers, although using different drivers isn't helping. The only thing that I think that it could possibly be is that maybe I need to get the TV card on its on IRQ for it to work properly. Can anyone figure out what is going on here?
